Firmware Update - GRAUPNER GR-18 Notice D'utilisation

I tail
Tail I-factor
Default setting: +70
The I-factor ensures constant pirouetting. Start with low values and only increase them until the pirouettes are constant.
If the values are too high, this will cause the tail to oscillate slowly.
D tail
Tail D-factor
Default setting: +15
The tail D-factor influences how the tail is stopped. If the tail bounces somewhat when the tail is stopped, this parameter
should first be increased in 5-degree increments to test the tail stop.
Collect. torque Cycl torque
Collect. torque Cycl torque
Default setting: +25 Default setting: +8
These two functions work best when they are set together. In the event of fast pitch pumping and swashplate movements,
the tail should remain stable even when load is applied. If the tail swings out briefly, the "Collect. torque" setting can be
increased until the tail stops.
On the ground, you can easily check whether the tail is working against the torque.
As a rule, "Cycl torque" should be set 1/3 lower than "Collect. torque".

Firmware update

Updates to the receiver's firmware are made via the telemetry socket using a PC running Windows XP, Vista or 7. You
will also need a USB interface (order no. 7168.6) and adapter lead (order no. 7168.6A or 7168.S), which are available
separately.
The programs and files required can be found in the Download area for the corresponding products at www.graupner.de.
Connect the adapter lead to the USB interface (order no. 7168.6). The connectors are reverse
polarity protected: note the small chamfers on the sides. Never use force – the connectors
should engage easily.
